Question

我正在使用Mule 3.8.1并且有一个csv文件，它在商店开放时间发送

Group Name,Group ID,Store ID,Store Name,Mon opening time,Tues opening time,Wed opening time,Thurs opening time,Fri opening time,Sat opening time,Sun opening time,Mon closing time,Tues closing time,Wed closing time,Thurs closing time,Fri closing time,Sat closing time,Sun closing time
DBLTD,DB1,STORE1,Main Store,9:00,9:00,9:00,9:00,9:00,9:00,9:00,20:00,20:00,20:00,20:00,20:00,20:00,20:00
DBLTD,DB1,STORE2,NYC Store,9:00,9:00,9:00,9:00,9:00,9:00,9:00,20:00,20:00,20:00,20:00,20:00,20:00,20:00

我需要使用Dataweave将它们映射到以下格式的JSON列表：

{
   "groupId": "DB1",
   "groupName": "DBLTD",
   "storeId": "STORE1"
   "storeName": "Main Store",  
   "openingTimes":
   [
      {
         "day": "mon",
         "openingTime": "9:00",
         "closingTime": "20:00"
      },
      {
         "day": "tues",
         "openingTime": "9:00",
         "closingTime": "20:00"
      }
      ...etc
   ]
}

我用来测试这个工作的XML流程：

<?xml version="1.0" encoding="UTF-8"?>

<mule xmlns:file="http://www.mulesoft.org/schema/mule/file" xmlns:dw="http://www.mulesoft.org/schema/mule/ee/dw" xmlns:metadata="http://www.mulesoft.org/schema/mule/metadata" xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation"

    <flow name="testFlow">
        <file:inbound-endpoint path="src\main\resources\input" moveToDirectory="src\main\resources\output" responseTimeout="10000" doc:name="File"/>
        <dw:transform-message metadata:id="e77b30f7-f9a2-4b97-82a9-23c186dc03cb" doc:name="Transform Message">
            <dw:input-payload mimeType="application/csv"/>
            <dw:set-payload><![CDATA[%dw 1.0
%output application/json
---
{
    GroupID: payload."Group ID",
    GroupName: payload."Group Name",
    StoreId: payload."Store ID",
    StoreName: payload."Store Name"
}]]></dw:set-payload>
        </dw:transform-message>
    </flow>
</mule>

有谁知道我怎么做到这一点？

尝试以下代码......

%dw 1.0
%output application/json
---
payload map {
    GroupID: $."Group ID",
    GroupName: $."Group Name",
    StoreId: $."Store ID",
    StoreName: $."Store Name",
    openingTimes: [
        {
            'day':'mon',
            'openingTime':$."Mon opening time",
            'closingTime': $."Mon closing time"
        },
        {
            'day':'Tues',
            'openingTime':$."Tues opening time",
            'closingTime': $."Tues closing time"
        },
        {
            'day':'Wed',
            'openingTime':$."Wed opening time",
            'closingTime': $."Wed closing time"
        },
        {
            'day':'Thurs',
            'openingTime':$."Thurs opening time",
            'closingTime': $."Thurs closing time"
        },
        {
            'day':'Fri',
            'openingTime':$."Fri opening time",
            'closingTime': $."Fri closing time"
        },
        {
            'day':'Sat',
            'openingTime':$."Sat opening time",
            'closingTime': $."Sat closing time"
        },
        {
            'day':'Sun',
            'openingTime':$."Sun opening time",
            'closingTime': $."Sun closing time"
        }

    ]

}
